I too bought the trial sample including the gum for $14.90. Not wanting the product I tried to get them by phone but couldn't get through so I mailed the package in the US Postal Service.
Subsequently they charged $39.95 to my credit card. I attempted to call them but there was a 70 min. wait so I again e-mailed them. They said they never got it back. I disputed the charge with Discovercard but they also got nowhere.
I am going to file a complaint with the Arizona Attorney General. For your info here's the link.
